STEEL RAIL.

To all whom it may concern:

Be it known that I, WILLI AM F. MoDADn, a citizen of the United States, residing at the city of Wilmington, inthe county of New Castle and State of Delaware, have invented certain new and. useful Improvements in Steel Rails, of which the following is a specification.

My invention relates to certain improve ments in the constructive arrangement of a two section steel rail spliced and bolted together and having a broad smooth tread surrelationship, to thereby constitute practically one continuous" firmly held rail throughout to 'receive the dead weight or strain brought to bear thereon; and second,

to provide a rail which in case of shearing or parting of the overhanging part. of the tread arising from any cause, maintains a. body surface sufiicient for a tread by reason of the webs in the lower grooved section engaging the tongue of the upper section and the webs of the lower section entering into bearing contact with the recesses of the upper section, the groove of the lower sec= tion being narrower at the upper open end 40 than at the base of said section.

The nature, scope and characteristic fea tures of my present invention will be more fully understood from the following description taken in connection wlth the ac companying drawings formmg part hereof,

in which V Figure 1, is a perspective of the two sections of the rail structurally embodying features of my invention, and showing Specifice .tionv of Letters Patent.

tural formation of the upper section of the rail.

Fig. i, is a vertical section therethrough on the line 3, 3, of Fig. 3.

Fig. 5, 1s a perspective view of the struc- 0 tural formation of the lower section.

6, is a vertical sectional view on the line 4, 4, of Fig. 5.

Fig. 7, is a perspective of the two sections of the rail splice-.1 of united to each other, m overlapping relationship. I

Fig. 8, is a plan view of a portion of two lower sections spliced together on the lines 6, 6 and 9. 9, of Fig. 7; and

Fig. 9, is a perspective view of a portion of a lower section, showing the recessed or offset base of such rail section.

Referring to the drawings. A, is the lower grooved section. of the rail with its side webs 8, 8, mounted on a suitable ,ti'e 15. Figs. 7 and S. B, is the upper section with its depending tongue 18. The groove 23, between the webs 8, 8. is narrower in the upper portion than at the base 19. as will be presenth fully explained. The under side of the head of the upper section B. of the rail is formed with longitudinal recesses 7. 7. for the upper edges of the side webs 8, S to engage, as

clearly shown in Fig. 2. and with the tongue 18. of the upper section in bearing contact with the base of the lower section. The narrowing of the groove '23. lockinglv wedges or holds the said tongue 18, securely in position. without regard to what shearing or other mishaps may occur to the overhanging portion of the tread portion of the upper section B. The two sections united to each other overlap in a longitudinal direction. as clearlv. shown in Figs. 1 and 7. The tongue of the section B. is offset at both ends. respectively. as indicated at 25 and 26, in order that complemental upper section; may be spliced or united therewith. for example. in the manner as clearly shown in Figs. 1. 7 and 8. In the portions 30. 31. where offset. as in Fig. 3, the upper sectionB, is provided with openings 10. and 11 and in between with openings 16, and also the webs of the lower section A, are provided with openings 16, 16 and 11 respectivelv as shown in Fig. 5, so that when said sections are assembled or joined together the respective openings will register with each other in both the tongue 18. and the webs 8. 8. to permit of bolts, not shown,being inserted therethrough 110 for tying solidly the rail sections to othe rail sections agalnst sidewise or other movement and thus to provide a SubstantmL'prac- .tical-ly continuous rail. In Fig. 9, the lower section A, is shown asofi'set at 27, 27, to allow a certain portion of the said section in position to rest on the tie 15., as shown at 29, 29, in Fig. 8, to give each end substan' tially an equal bearing surface on the said tie 15; and moreover to afford the tongue 18, of the section B, an equal bearing on the bottom of'the groove of the said lower sectionA.

Having thus described the nature and objects of my invention, what I claim as new and desire to secure by Letters Patent is A rail, comprising two sections, one see- 'tion haxing a tongue "with right-angular ofi"- sets at the respective extremities in reverse form in respect to each other and the other section provided with two vertical webs with the space formed by said webs from the base of said section contracted vertically so as to wedgingly engage the tongue-section with 25 webs and tongue of the respectlve sections 3 in position to lock the same to each other,

substantially as described.
